DCP-LETT-8987

From:
Charles Robert Darwin
To:
John Scott Burdon Sanderson, 1st baronet
Date:
25 July 1873
Source of text:
University of British Columbia Library, Rare Books and Special Collections (Darwin - Burdon Sanderson letters RBSC-ARC-1731-1-11)
Summary:

Describes his recent work on Drosera digestion of organic materials, e.g., albumen and gelatin. Edward Frankland has given CD a rough test for pepsin. Some plant extracts cause as much inflection as meat. Has found some reversible inflection with heat and perhaps some heat rigor. Has measured the extreme sensitivity of Drosera with very dilute solution of ammonium phosphate.
